Folks,
Given that QF management now publicly admits that the N777X will be 43% less fuel, per seat, on average, compared to the A380 (with the B787-8/9 and current B777/A350 also beating the A380 hands down on the same criteria) and the fact that the cost of fuel, even at present prices, is not trivial, I will believe that when I see it.
Tootle pip!!
